Schiit Midgard

The short version

What to know.

Schiit's $219 discrete headphone amp and preamp, and the replacement for the op-amp Magnius. Almost everything about it is agreed on: 4.8 W into 32 ohms is far more power than the price implies and drives everything from IEMs to a Susvara, the US-made metal chassis with Neutrik connectors and an Alps RK27 potentiometer is a class above, channel tracking stays clean at low volume, sensitive in-ears are quiet, and the bench calls it effectively transparent. The argument is entirely about Halo — the mixed-mode feedback on the front 4-pin XLR, which puts the headphone driver inside the feedback loop. Rather than prove it, Schiit gave free units to anyone with a measurement rig, and three people published: two found no reliable difference between the Halo and standard outputs, one found a small distortion reduction on low-impedance dynamic drivers at high volume and doubted it was audible. Several reviewers nonetheless hear the Halo output as more open and spacious, and one circuit analysis explains why the effect should be near-zero on high-impedance headphones and largest on low-impedance dynamics — which is roughly what the one positive measurement found. Practical limits are real and consistently flagged: the preamp outputs never mute when headphones are plugged in, the Halo jack carries about 2 ohms of output impedance against under 0.1 on the 1/4-inch, there is no remote and no 4.4 mm, and owners on 230 V mains have reported a ground-loop buzz that US owners do not hear.

About this product

A headphone amp and preamp with no DAC option — it does not take Schiit's internal DAC cards, so it is neither the one-box Magni Unity nor a smaller Asgard. It replaced the op-amp Magnius. Despite balanced XLR inputs and outputs it is internally single-ended: the front 4-pin XLR exists to enable Halo mixed-mode feedback, not to add power, and both headphone jacks put out the same 4.8 W into 32 ohms.

In Norse myth Midgard is the earth — the realm of mortals, not gods — and Schiit picked the name deliberately for the amp that replaced the op-amp Magnius. It is fully discrete, made in Texas, puts out nearly 5 watts into 32 ohms, and costs $219. On the ordinary questions of power, build and price, it is about as uncontroversial as budget audio gets.

The interesting part is the front panel's 4-pin XLR. It carries Halo, a mixed-mode feedback topology that folds your headphone's own driver into the amplifier's feedback loop — which, in theory, lets the amp correct the transducer rather than just feed it. Schiit declined to prove this. Instead the company shipped free units to anyone with a measurement rig willing to publish whatever they found. Several people took that deal, and their results are the reason this amp is worth an argument.

A good fit for

  • First serious desktop rigs that want one amp to cover IEMs and full-size headphones alike
  • Owners of hard-to-drive headphones on a budget — the power here is genuinely unusual at the price
  • Desks where headphones and powered monitors share one volume knob and two switchable sources
  • Listeners with low-impedance dynamic headphones and a balanced cable, who want to try Halo where the evidence says it is most likely to do something
  • Buyers who value US manufacturing, real Neutrik and Alps parts, and direct support over spec-sheet supremacy

Think twice if

  • You are buying it for Halo and want the feature proven before you pay for it
  • You need a DAC in the same box — the Midgard has no card slot, so budget for a separate one
  • You want your speakers to mute when you plug in headphones
  • You need a remote, a 4.4 mm jack, or a display
  • You use very low-impedance multi-driver IEMs on the 4-pin output, where about 2 ohms of output impedance can shift the tuning — use the 1/4-inch instead
  • You already own a capable amp; several owners describe this as an excellent entry-level step rather than an endpoint

The reviewer consensus

1 Strong agreement5 Mostly agree1 Divided opinions

Common ground8

  • Far more power than $219 suggests — 4.8 W into 32 ohms, enough for anything short of the hardest planars
  • Both headphone jacks deliver the same power; the 4-pin XLR adds Halo, not headroom
  • Measurably transparent on the bench — flat response, distortion and noise below audibility

Points of contention6

  • Does Halo actually do anything you can hear? Reviewers describe an obvious change in staging; three independent acoustic measurements found either nothing or about 0.3 dB
  • If Halo does work, on what? The circuit analysis and the one positive measurement both point to low-impedance dynamic drivers, not planars or high-impedance headphones
  • Whether the wider soundstage from the 4-pin output is Halo at all, or simply the better channel isolation that output brings

The least arguable thing about it, and the reason it gets recommended so freely. 4.8 W into 32 ohms from a $219 box is more than most of the class manages, and unusually both jacks deliver it — the 4-pin XLR adds Halo, not headroom. Reviewers drove Susvaras, HEDDphone 2s and HD 650s without running out, and one measured more into 300 ohms than Schiit claims. The single recurring caveat is at the very bottom of the impedance range, where the protection circuit intervenes early, and at the very top of the volume range with the least efficient planars, where the pot runs out before the amp is embarrassed.

Measured

Schiit rates 5.5 W into 16 ohms, 4.8 W into 32, 3.2 W into 50, 750 mW into 300 and 375 mW into 600, with two gain settings (0 dB and +14 dB). ASR's bench confirms ample output on both jacks and measured about 822 mW into 300 ohms, above the published figure; distortion stays extremely low right up to the point the protection circuit lifts the output. Output impedance is under 0.1 ohm at the 1/4-inch jack but approximately 2 ohms at the 4-pin XLR, because Halo senses current through a series resistor there.

vs. listeners — Everyone agrees the headroom is there; the only friction is that ASR judged the protection circuit to intervene sooner than necessary into low impedances, while reviewers running normal loads never reached that limit.

As of

What to keep in mind 6

  1. A read of where the reviews land as of August 2026. The Midgard arrived in late 2023, so most of the writing about it is a couple of years old and the budget desktop field has moved since.

  2. The Halo question is genuinely open. Two careful acoustic tests found nothing and a third found a very small effect on some headphones, while several experienced listeners describe an obvious one. Both readings are laid out above, and which weighs more is a personal call.
